Abstract
A design method of a transformer repeats following steps until a preset condition is met: calculating an output voltage of each secondary winding according to a phase shift angle and a number of turns of the each secondary winding; obtaining a difference between output voltages of each secondary winding pair in a secondary winding set; adjusting the phase shift angle of at least one secondary winding in the secondary winding set; and obtaining a final number of turns for the each secondary winding according to a resultant phase shift angle corresponding to when the preset condition is met; where the preset condition is that the difference between the output voltages of any secondary winding pair in the secondary winding set is less than or equal to a preset threshold.
